Abstract
A method and apparatus for forming an image is provided by visualizing a latent image on a photosensitive member with a toner having an electrical resistance, transferring the visualized image to an image recording medium, cleaning with a cleaning blade a residual toner adhering to a surface of the photosensitive member after the transfer of the latent image to the image recording medium, and charge injecting a biasing voltage of a predetermined magnitude to the residual toner with a conductive polyester film, whereby at least part of a surface potential of the photosensitive member is removed. The conductive polyester film is fixedly attached to a tip end of the cleaning blade.
Claims20
An image forming apparatus comprising:
- a photosensitive member for forming thereon a latent image;
- a developing apparatus for visualizing said latent image on said photosensitive member with a toner having an electrical resistance;
- a transfer device for transferring said visualized latent image to an image recording medium;
- a non-conductive cleaning blade for cleaning residual toner adhering to a surface of said photosensitive member after the transfer of said visualized latent image to said image recording medium by said transfer device;
- and
- a conductive film fixedly attached to a tip end of said non-conductive cleaning blade for applying a bias voltage of a predetermined magnitude to said residual toner, said conductive film being applied with said bias voltage to charge said residual toner remaining on said surface of said photosensitive member by charge injection from said bias voltage applied to said conductive film, whereby at least part of a surface potential of said photosensitive member is removed.
An image forming apparatus, comprising:
- means for forming a latent image on a photosensitive member;
- means for visualizing said latent image with a toner having an electrical resistance on said means for forming;
- means for transferring said visualized image to an image recording medium;
- means for cleaning a residual toner remaining on a surface of said means for forming after the transfer to said image recording medium;
- and
- means for charge injecting a bias voltage of a predetermined magnitude to said residual toner, whereby at least part of a surface potential of said means for forming is removed,
- wherein said means for applying a bias voltage includes a conductive film fixedly attached to a tip end of said means for cleaning.
